27th March 2020 - Before we get to the rest of the questions - a few facts which should help imminently;

  • We ship from the UK - worldwide. Before ordering - Please check such research substances are legal in your country prior to ordering. This is not our responsibility, it is impossible for us to keep track of the importation laws in every country.
  • Our hours of operations are Monday - Thursday 9am-5pm UK GMT and Fri 9am-12pm UK GMT. Emails or calls sent after this time will be responded to Monday. At times, we can be extremely busy, so please read through the site info and your order status and if you still need help, please email us: peptexlaboratories@gmail.com - we have a new office number however this will not be active until the 2nd June 2020 - our new number will be (+44) 01494 473371
  • If you have been emailing, and received no response, it could be that your email has landed in our spam/junk box - please check this prior to calling or writing.
  • We have a 2-3 day lead time on email - we apologise for the slight delay. Note we do not answer calls over the weekend, so please leave a voicemail and we will check it and get back to you the next Business day.
  • Yes we are a 100% legitimate company, registered with companies house as a Limited Company in England, authorised to use Amazon Pay and other Merchants and unlike 99% of sketchy peptide sites, we test our products via a 3rd party, have a landline to call and welcome feedback of every type to help us improve and develop. Our company is a Limited company trading in England and Wales company number 11743599.
  • We are passionate about the research field of Health and Life Sciences - that is what we are focused on and stock - our aim is to provide researchers with the best quality research products available and we go to great expense in doing so. Our company was born out of a passion to provide the industry with a solid, 100% reliable supplier of research material and laboratory equipment and we continue to work towards this goal daily.

PLEASE READ THE BELOW CAREFULLY IT SHOULD ANSWER 99% OF ANY QUESTIONS 

Pre Orders? What is this about?

We now offer all products (soon to add more) on a pre-order basis. If your order is in stock, we will dispatch it within 1-2 working days of receiving cleared payment. If it’s not, then we will order the peptide for you, have it synthesised and sent to us. This process can take 5-8 working days, so if your unhappy about this, please do not order. It should show at checkout if your chosen product is in stock or not, if not you have the choice not to order. We endeavour to fulfil all orders we receive ASAP.

What is a peptide? 

Peptides are natural biological or artificially manufactured short chains of amino acid monomers linked by peptide bonds. The covalent chemical bonds are formed when the carboxyl group of one amino acid which reacts with the amino group of another. 

Are they legal?

This would be down to the context in which they are used. For in-vitro, laboratory research use they are, broadly speaking, entirely legal. For human use, while not illegal as many individuals choose to self research, we would never advise using a peptide that is still in its developmental/trial stages. It is akin to Russian Roulette and we strongly advise against human use All products we sell are for research use only.

How long will take for my parcel to arrive?

This is dependent on when and where you have ordered from geographically speaking and payment method. For all customers – we typically process your payment and dispatch within 24-48 hours on business days only. For our international customers, it can take between 1-3 days for your payment to clear if paying by bank transfer, once confirmed however we always endeavour to ship your order within 24 hours. We accept Amazon Pay and Bitcoin which is a global and instant method of payment and one which we would advise our International customers to use.

We take pride in our rapid process and dispatch of all customer orders.

Do I need to sign for my parcel?

We send parcels by Royal Mail 1st Class Recorded/Special Delivery and Royal Mail International Tracked. Both require a signature. If you do not want or are unable to sign for your package, please make a note in the comments section during checkout and we will send your order through either 1st Class regular post or International 1st class airmail. Both do not require any signature however it also means packages cannot be tracked and it is for this reason we are unable to accept any loss for packages lost in transit which cannot be proven. We will ensure to take relevant pictures of your parcel, and obtain proof of post.

For Express International Courier Shipments, whereby we have already discussed a confirmed shipping options, a signature, email, and phone number is required along with a full shipping address. We often utilise DPD for our express courier who typically take 2-4 working days worldwide.

Where do you ship from?

All of our parcels are shipped from the UK, allowing prompt transit into Europe and Internationally. It also allows for extremely quick UK delivery by Royal Mail.

Do you ship discretely?

All of our orders are shipped with just your address only and our return details and no other visible markings to discern contents, unless we ship outside of the EU, in which case a customs declaration is required. 

Some of my labels are different in colour and the lids are not always purple, why is this?

Since our formation, we have evolved the look of our brand and we have 3 varieties of label. A darker purple one which we started with and stopped using in October 2018. We then used what we thought was a better-quality label supplier who provided us with a lighter colour purple label but quality wise, not the best. Our new labels are white, with our logo and has some silver metallic elements.

Lid colour is dependent on batches and order volume. Our laboratory requires a minimum 500 unit per item order to produce custom lid colours, so on occasions where we may not need 500 items, they will send us the same product we ask for but with whatever label colour they may have to hand. This is why sometimes the lids are different colours. Aesthetics aside any peptides we purchase have to conform to a 99%+ minimum purity requirement, and we receive test data to verify this. We will also be providing third party test data to further verify this. Our focus is and has always been on quality and service. So please do not be alarmed if you get 2 products of the same type one week with different colour lids to the next week. It means zero, simply a newer/older batch and 99% of our batches we keep in stock are never kept in stock longer than 3 months.

How should I store and handle my peptides when they arrive?

When peptides are received, ensure they are kept in a cool, dark place. For best preservation, store them under refrigerated temperatures of 4°C or colder, away from bright light. Dry peptides are stable at room temperature for weeks to months, but for long term storage up to 4 years, -20°C is preferred - however DO NOT freeze/defrost and re-freeze. As a rule of thumb when you receive your order, please store in the fridge even before reconstitution. It is best to do everything possible to keep your peptide in the best possible condition.

How do I pay for my order?

At present, we accept bank transfer for all orders, including for our International Customers. Our account accepts pament from the UK, Europe and Worldwide. We also accept bitcoin and Amazon Pay which is our mos popular option.

Please be careful to follow the on-screen payment instruction. Any queries please email us: sales@peptex-labs.com


I love your products and want to make a little extra cash by providing them to those I know will love them. Do you offer a commission/affiliate type scheme?

Yes, we do! Please scroll to the bottom of the home page and in the footer, please click the affiliate link and register from there but remember to ensure you carry out your due diligence on your future client base. We payout on the 1st day of every month - you can choose to be paid back by PayPal or with Store Credit. Be sure to click the link on the home page, in the footer - 'Become an Affiliate' and put in all your data. We have some affiliates that do very well just by posting on forums with their affiliate code which is provided once we approve you.

What postal method do you use?

UK – Royal Mail 1st Class Signed For for orders below £50, Special Delivery for orders between £50-£500. For orders above £500+ we use DPD courier next day.

International – Royal Mail International Track and Sign or if no signature required, then just Royal Mail Tracked or if you do not want it tracked, then just Royal Mail First Class International. For orders above £500 we use DPD courier or a courier of your choice.

For International customers who would like their order delivered swiftly, we would recommend DPD express – we find it is far quicker than Royal Mail, however unless your order is above £500 it is a little more expensive but arrives to the US/Australia and Europe within 2-4 working days.

What do I need to mix/ reconstitute my peptides with?

Bacteriostatic Water or Acetic Acid, both are available in 10/20ml variants on our website. The most popular option is Bacteriostatic water which we sell in 10mland 20ml varieties. IGF protein varieties need Acetic Acid as a diluent/reconstitution agent. We find the most popular diluting agent to be Bacteriostatic Water as it prolongs the active life of the peptide, provided it is kept at the right temperature.

What happens if customs seize my order?

Before ordering, please ensure you have checked the regulations with regards to the importation of your chosen products. We are unable to be held accountable if your goods are seized and they are not permitted in your country.

That said, if there is no issue and your order has been seized for other reasons, please contact us by email with proof of seizure (normally you would receive a seizure letter) We will then make some checks and will do all we can to help resolve any issues – whether it be reshipping or offering a store credit. We do provide a document within packages specifically for the intended countries Border Force/Customs Department in the case the pack is opened, specifying what the items are, that they are used strictly for research and investigatory purposes only and that they are not in any way intended for human consumption.

However, if your pack is seized, and is strictly illegal even for research use, we cannot help but will look to do what we can to aid in recompense.

Do you offer any refunds?

No - this is due to the nature of the product, its volatility and storage requirements. If we send something with a clear manufacturing or shipping error, then of course we will put this right but aside from this, we cannot offer a refund due to fragility of the nature of peptides.

Do you sell other products not listed on your site?

We work closely with our suppliers to provide the latest peptides, SARMS and Nootropic / research chemicals available.  We can offer a huge range of peptides, including cosmetic/beauty peptides and health and life science peptides, if there is anything you require but is not listed on our site, please contact us and we will make the relevant enquiries and do whatever we can to help you. We are UK based, so we are subject to certain laws such as the psychoactive substances act, so there will be some products which we are not allowed to sell, but we check legality before offering any such substances on site. Our partner laboratory often custom synthesise peptides for us, providing you have the sequence needed to handed, molar mass and any other relevant info needed.

What are Peptex Laboratories Peptides Used For?

Peptides and Research serums are manufactured and sold to be used in a laboratory research setting. This can be via Educational, Research or even home researchers. None of our products are intended for, nor are they manufactured for, diagnostic or therapeutic purposes in humans. Peptex Laboratories reserves the right to require additional verification of proper intent prior to fulfilling orders. Any orders that we feel aren’t for the specific intended purpose laid out in our Terms and Conditions will be denied.  Truthfully, if you are asking this question then you shouldn’t be ordering from Peptex Laboratories.

What are the purity levels of the peptides you sell?

Peptex Laboratories will never sell a peptide that is less than 98% in purity. Many of our smaller peptide chains are well into the 99% purity range. Our supplier has manufacturing abilities that are quite often beyond the scope of smaller companies and therefore are able to achieve very high purity levels. Proteins such as IGF-1 LR3 are always above 95% purity with our receptor range in excess of 99%. Purity of a peptide is determined by the amount of the target peptide by HPLC at 214nm. This is where the peptide bond absorbs. Residual salts and water will not be detected by UV Spectrophotometer. Impurities that are usually found after peptide synthesis may consist of deletion sequences, truncated sequences and de-protected sequences and some peptides may, due to their structural sequence, require additional preservative, so high 98%+ is what we aim for and never below this. We have uploaded third party testing, our own lab test results and even customers who have tested our products and sent us results which we then post with their permission.

If A Peptide Is 98% In Purity Then What Is the Remaining 2%? 

The purity level indicated on a COA is simply a measurement of aminos that made it into the proper chain to form the peptide. The left over 2% are simply aminos that, for whatever reason, didn’t make it into the proper sequence or it means the peptide sequence required additional preservative by nature meaning it cannot be 100% pure - but we do our best to get to 100% where possible.

Where do you source your products?

We work closely with our laboratory which is based within the European Union and we work with a University within the UK who aid our testing as well as a new lab in Switzerland who will be testing our SARMS. We have used DGM In China for other tests where UK/EU companies couldn't support the testing of certain items due to the complexity of machinery needed or for legal reasons.

Obviously, we do not wish to disclose the specific location of our supplier, as we run a business based on the relationship we have built up with them and it would be fairly simple to work out the laboratory in question with some simple Googling, putting our profitability and business at risk! Our business is based around our supplier relationship, so we hope you understand our reasons for not being too specific.

All of our products go through HPLC chromatography and Mass spec analysis and our manufacturing facility is regulated by GMP (Good Manufacturing Process) and is ISO 9001 certified.

All products we receive come with a COA and we currently conduct batch testing quarterly, we last sent off 12 prducts for testing at the end of October 19/early November 19 and have published the results on site. We have a new lab in Europe willing to test our products who provide each test result with a unique serial code, which can be verified on their own website. We intend to send our next batch to them for the end of March 2020.

Can you offer bulk/wholesale deals?

Yes, please email peptexlaboratories@gmail.com for a price list. We offer bulk prices on peptides and SARMS.

Is it true you sell on eBay and Amazon too?

We used to sell on both platforms but as of February 2020, we no longer sell our products on either platform, due to being targeted by competitors and trolls who we have called out when Amazon have worked out the individual have not even placed an order! We may go back to Amazon sales in the future but for now we are focused on direct sales on our website.

Why do some peptides come in a puck shape and others look like loose powder?

Each aliquot of peptide is deposited into each vial via machine. The vial is then stoppered and moved inside the lyophilizer. Once in the lyophilizer, the vial is then given a nitrogen flush to clear any contaminates. This is the phase that will determine the appearance of the contents.


Sometimes the water vapour can escape the vial where it goes from a solid to a gas without every going through a liquid phase. This will make the contents adhere to the sides of the vial leaving very little to see by the naked eye. Other times, depending on several other factors including temperature, the appearance can look like a solid puck, a few smaller pucks, a powder material, or even just a few specks, but the amount of actual material and quality is the same. Please remember 5mg for example is 5 MILLIGRAMS - not grams - 5 mg is a tiny amount of visible powder to the eye, so if the vial does not look full for example, that does not mean the product does not contain what it should.

When freeze drying products without any matrix (sucrose or mannitol for example) sometimes the residual water of hydration will cause a collapse via hydration of the product before it fully dries. In other words, when the water from the ice crystals is removed what remains prior to secondary drying (when the chamber is warmed) can combine and solubilise the remaining material causing it to collapse. Sometimes it forms crystals and sometimes it forms films dependent upon how much there is local melting and what the temperature and vacuum levels are at the time of the collapse.

Why don’t you answer my emails?

We have had past email inbox issues, from having our inbox attacked with malicious spam (1000's of emails a day of spam containing virus links) to being so busy we have built up a backlog. Please now use our gmail address, which while it does not look so professional, it enables all customer emails to come through without any hassle or concern. peptexlaboratories@gmail.com

What happened to your Instagram account, you had tens of thousands of followers?

We lost 3 accounts, and I think this is due to us looking like we are promoting the use of such products for humans. We have ceased the use of Instagram for the time being.
